GAS-SAVER FOR EXPLOSIVE-MOTOR-S.

To all whom it may concern Be it known that I, GEORGE E. THOMPSON, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in (ias-oavers for Explosive-Motors; and I do declare the following to be a clear, full, and exact description of thesame, reference being had to the accompanying drawings, and to the characters of reference marked thereon,

part of this application. This invention relates to improvements in explosive motors and particularly to the fuel intake mechanism thereof, the object'of the invention being to produce an aerator for the fuel adapted to supply auxiliary air to the fuel at such times as the same is needed and automatically cut the same off at such times as it is not needed. Said air sup' ply is controlled with the advancing and retar-ding of the ignition spark whereby; the

valve showing it in closed position.

air may be admitted with an advance spark or shut off with the retarded spark as is proper according as speed or power is wanted from the motor.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure l is an end view of a motor showing my improved attachment thereon. Fig. 2 is a sectional view of my improved air Fig. 3 is a side elevation of the complete air valve. Fig. 4 is a sectional view of the valve showing it in open position.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the motor, the numeral 2 the manifold fuel intake pipe thereon leading from the carburetor 8. My improved valve comprises a tubular member 5 screwed into the pipe 2 between the carburetor 3 and the motor 1. Said member. 5 has an air inlet 6 controlled by a piston or plunger 7 having a rod 8 projecting through the closed Specification of Letters Patent.

end of the member 5. A flexible wire or cable 9 cornectsthe rod 8 with the timer 10 of the magneto 11, as at 12, whereby when such timer is advanced to give the quickest sparking ignition, the cable may be pulled to pull on the rod 8 to operate the piston 7 whereby communication will be opened through the opening (3 and member 5 into the pipe 2 to admit auxiliary air which may be moistened as will presently appear. Then when the spark is retraded and the timer 10 moved correspondingly, the cable 0 will slacken, as shown in Fig. l, by dotted lines, and the suction in the motor will pull the plunger 7 forward 'to shut off communication from the opening (3, thus shutting off the auxiliary air supply.

As is a well known fact, moist air is of much greater value when applied in the manner specified and hence I provide the over flow pipe 10 of'the radiator of the mo tor with a coil 11 at its lower end and between said coil 11 and the bottom of the radiator 12 I provide a pipe 13 which leads and opens into the opening 6 whereby the air taken through the opening 6 will be moistened for the reason that there will always be a certain amount of moisture in the pipe 10 and coil 11 due to'the steaming of the water in the radiator 12.

On the end of the member 5 is a removable cap 5 and disposed around the member 8 within the member 5 are a plurality of shims or washers 14 whereby with the removal or insertion of one or more of said Washers, the movement of the member 7 will be limited to adjust the size of the opening through the inlet 6 in order to allow the proper amount of air for any particular type of motor to give the best results.

As will be noted, by means of my im proved structure, the auxiliary air is given to the fuel on a fast spark and shut oil on a slow spark as is proper to give'the desired fuel for speed or power. 1

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

-leading from the carbureter to the motor,

and an ignition system, such ignition system having a rotatable timer, of a valve commu nicating with said pipe between said carbureter and said motor, such valve comprising a casing having an opening in its side,a piston slidably mounted in said casing to control the communication between said open ing and said casing, a stem on said piston and a flexible cable-connected between said stem and said rotatable timer, as described.

2. A device of the character described comprising the combination with an explosive motor having a carbureter and a pipe" leading 'from the carbureter to the motor, and an ignition system, such ignition system having a rotatable timer, of a valve communicating with said pipe between said carbureter and said motor, such valve comprising a casing provided with an opening in its side, a heating medium, means communieating from said heating medium to said (Iopies of this patent may be obtained for opening, a piston movable in said casing and controlling the size of said opening, a

timer, as described.

.3. A device of the character described comprising the combination with an explosive motor having a carburetor and a pipe leading from the carbureter to the motor, and an ignition system, such ignition system having a rotatable timer, of a valve communicating with said pipe between said carbureter and said motor, such valve comprising a casing having an opening in its side, a 'cap on'the end of said casing, a piston movable in said casing, a plurality of shims removably disposed within said casing between said piston and said cap, a stem on said piston and means connected between said stem and said rotatable timer whereby said piston will move with the movement of said timer, as described.

In testimony whereof I 'aflix my signature in presence of two witnesses.
